Patent

CA 2022964

An improved trocar sleeve is disclosed for use in laparoscopic surgery. The sleeve is provided with an expanded mushroom hinge at the first end of the sleeve inserted into the abdominal cavity. The mushroom hinge can be expanded within the abdominal cavity to abut against the inner surface of the abdominal wall to hold the sleeve in place. A split seal having a concave shape facing the first end of the trocar sleeve is provided to prevent loss of pressurized gas from within the abdominal cavity through the sleeve as the pressure of the gas itself urges the first and second seal lips on opposite sides of the slit in the seal into sealing engagement.
